The authors of a study looking at the effect of alcohol intake on colorectal cancer reported an incidence rate ratio of 2.1 (95% CI: 2.05-2.31) when comparing heavy drinkers to light or nondrinkers. The authors of a second study examining the effect of green tea consumption on colorectal cancer reported an incidence rate ratio of 0.85 (95% CI 0.56-1.75) when comparing green tea drinkers to nondrinkers. How do you interpret the findings of both studies? Discuss the i) direction, ii) strength and iii) statistical significance for BOTH associations
